詳細內容：LCP3000EZ 工業進化本質在提升質量，而非降低成本 　　人力成本被認為是導致近年制造業競爭力下降的原因，但李永利認為，制造業不能僅僅盯著制造環節的成本，應該更加注重供應鏈成本。而數字化制造從一開始就不僅僅是為了降低成本，最大的目的在于提升質量，而高質量并不意味高成本。 　　近年，國內制造業遭遇的發展瓶頸中，人力成本的上漲，被認為是導致制造業競爭力下降的重要原因之一。 　　“很多制造業的企業主都喜歡談控制成本，但在西門子看來，質量才是企業的第一競爭力。”李永利反復強調，“質量第一”一直是西門子成都工廠戰略目標首位，而這也是客戶眼中最重要的價值。 　　事實上，在他看來，很多時候企業面臨的并不僅僅是制造環節的成本，而應該更加注重供應鏈的成本。因為，即使在勞動密集型企業中，人力成本畢竟只是占據一定的比例，而不是成本的全部。 　　以一個簡單的例子來看，當一款產品出廠時，它同時擁有了兩個價值，一個是出廠價值，一個是到客戶手中時的價值。“中國很多工廠生產出來的產品，出廠價值不高，但到客戶手中的價值就很高，這就是供應鏈的問題。”李永利說道。 　　盡管他并不認可僅僅盯著成本來談論“工業進化”，但李永利強調，數字化制造本身所帶來的高質量并不代表是高成本。 　　高質量在工業制造領域的重要性不言而喻。作為耐用品的工業產品，比如一款海上風力發電機的產品，一旦出現問題，不僅造成的損失不可估量，而且需要動用到直升機維修，維修的后期成本也非常高。 　　為此，在實現質量提升上，數字化制造首先是借助自動化產線上的機器充當“糾錯官”的角色，比如當工人少擰了一顆螺絲，機器會自動發出警示，阻止產品進入下一個環節，通過機器的協助，減少人的出錯。 　　但在西門子看來，通過機器的“檢查”杜絕人在制造過程的差錯，這只是保證產品質量的基礎一步，由制造質量、研發質量以及原材料質量組成的產品質量中，更需要的是借助數字化制造去保障研發質量和原材料質量。 　　尤其是如何保證原材料質量，一直被認為是制造業界最具挑戰性的一個課題。 　　在SEWC的數字化制造中，一個很重要的方式是對原材料進行可溯源式的管理。也就說，在這座工廠內，當來自各地的原材料被運送到車間后，所有的原材料都擁有了自己的“身份證”。這個身份證可伴隨原材料進入生產線，在每一個流程中，都會被相應的設備進行數據的采集和跟蹤，并最終儲存在后臺的數據管理中。 　　這意味著，一旦有原材料的質量出現問題，工廠可以馬上查找到這一批次的原材料在什么時間點，已經走過哪些生產流程。李永利表示，無論客戶在今后什么時間反饋質量問題，工廠依舊能夠拿出完整的數據，對這些原材料進行追溯，從而保證原材料的質量。 　　走向工業4.0，管理自動化才是關鍵 　　在數字化制造的階段，通過數據交互，已經能夠有效地提升管理效率。但要衡量是否真正走向工業4.0，不是看生產線自動化水平的高低，而是看管理水平的高低。實現管理的自動化，需要實現管理上人完全聽命于“電腦”，這才是智能制造的未來。 　　事實上，這樣一座代表著數字化技術如何改造工業制造的前沿工廠，距離工業4.0愿景下的智能工廠仍有距離。在工業4.0的研究中，智能制造和智能工廠一直被認定為兩大研究主題。其中，關于智能工廠，被描繪成是一個分散的、具備一定智能化的生產設備，在實現了數據交互之后，形成了高度智能化的有機體，實現虛擬世界和物理世界的融合。 　　在SEWC中，關于推進數據交互的工作一直未曾停止過。但對于數字化工廠與智能化工廠之間的差距，李永利認為，最關鍵的一點在于是否真正實現管理的自動化。 　　西門子安貝格工廠 　　德國安貝格電子工廠作為西門子全球首個數字工廠，是SEWC的姐妹工廠。該工廠從1989年投產至今，占地面積與員工數量幾乎都保持不變的情況下，產能卻比25年前翻了8番。 　　無論是德國的安貝格電子工廠，還是SEWC，這兩家工廠每年要生產幾百萬件產品，更考驗管理的是，產品類別也達到了上千種。當涉及的產品類別眾多，而且客戶訂單數量和周期不同，如何去做好訂單管理，以及如何連通訂單管理背后的生產制造、物流配送等多個環節，考驗的正是管理的智能化水平。 　　相比普通工廠單憑人力做訂單的跟蹤管理以及后續生產的調度安排，SEWC的數字制造中，當ERP系統收到訂單，MES系統將自動進行生產安排，包括通知采購部門、財務部門等，整個生產包括后期的發貨全部由工具充當“指揮”，自動完成。 　　如果從勞動力的角度看，李永利認為，盡管在生產線上并不認可一味地以機器代替人，減少藍領工人，但在管理“白領”群體時，在管理層面，他認為可以更多地借助機器，積極使用更多的軟件。 　　“因為未來制造業的衡量標準不是生產線自動化水平的高低，而是管理水平的高低。”他認為，在中國制造實現智能化提升的路上，相比硬件設備，管理水平的高低才是影響中國企業能否實現工業4.0的關鍵。他強調，要真正實現工業4.0，一大標準是管理水平達到了一定的高度，甚至實現了自動化。 　　“如果管理實現自動化，也可以理解為，工廠的所有決策和指令都聽命于電腦，連人也是聽命于電腦。”李永利說道，但實現這一步顯然并不容易，至少從理念上，如何讓人完全聽命于電腦，則需要一場思維變革。 　　但至少，數字工廠作為實現智能工廠的必經之路，已走出了第一步——讓機器代替人去做更多的決策。而等到工廠內，真正能用自動化替代人進行管理，人聽命于“電腦”的話，那么，電腦背后所代表的制造的未來，也將來到眼前。 Wavetek 131A VCG Generator Operating Service Manual Wavetek 135 Sweep Generator Operating Service Manual Wavetek Test and Measurement Inststrum. 1992 Catalog Wavetek 132 Noise Generator Operating Service Manual Wavetek 134 Sweep Generator Operating Service Manual Wavetek 145 Funct Generator Operating Service Manual 2 Wavetek HD-160 True RMS Digital Multimeters Wavetek 1983 Test & Measurement Instrumentatio​n Catalog Wavetek 1976 Catalog Wavetek Generation & Measurement Equipment Catalog Wavetek 1978 Generation & Measurement Equipment Catalog Wavetek DM73A Digital Multimeter Wavetek 142 VCG Generator Operating Service Manual Wavetek 110/111Generat​or Instruction Manual Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek 1038-V13 Operator/Servi​ce Manual *Original* SHIPS FREE!
